Most real estate regrets aren’t caused by bad luck or impossible markets. They’re caused by predictable, avoidable mistakes—the same ones I see repeated across different clients, different price points, and different market conditions. Here are the ten I encounter most often, five on each side of the transaction.
Bottom Line Up Front: The majority of buyer and seller mistakes stem from one of two causes: acting on incomplete information, or letting emotions override a rational framework. Understanding these patterns is the first step to avoiding them.
5 Buyer Mistakes
Mistake 1: Treating List Price as Market Value
A listing price is a marketing decision, not an appraisal. In the GTA, some sellers deliberately underprice to generate competition and drive the final price higher. Others overprice to anchor buyer expectations. The list price tells you almost nothing about what a property is actually worth.
The fix: ask your agent for a Comparative Market Analysis (CMA) before settling on an offer price. Comparable sold data from the past 3–6 months is the only reliable benchmark.
Real Example: A townhouse listed at $999K—deliberately below market to invite multiple offers—sold for $1.31M in one evening. Buyers who based their budget on the list price were completely unprepared.
Mistake 2: Shopping Before Getting Pre-Approved
House-hunting without a mortgage pre-approval is like grocery shopping without knowing your budget. You might fall in love with a home that’s 30% above what you can borrow, then spend months searching for something comparable at a lower price point—a frustrating and inefficient process.
A written pre-approval takes 3–5 business days and establishes your actual borrowing capacity with verified documentation. Do this before your first serious showing.
Mistake 3: Waiving the Home Inspection Without a Plan B
The 2020–2022 bidding-war era normalized waiving inspections. Buyers paid the price—sometimes literally tens of thousands of dollars—when undisclosed issues emerged after closing. In Ontario, where home inspector licensing is unregulated and seller disclosure requirements are limited, inspection protection matters more, not less.
In 2026’s more balanced GTA market, including an inspection condition is increasingly feasible. Even in competitive situations, pre-inspections (conducted before offer night) allow you to bid confidently and conditionally.
Mistake 4: Emotional Bidding Beyond Your Ceiling
Multiple-offer situations create an artificially competitive atmosphere. The fear of losing to another buyer is real—but it’s not a good reason to overextend your finances. Buyers who haven’t set a hard maximum price before entering an offer situation routinely push past their comfort zone in the moment and spend months in buyer’s remorse afterward.
Set your ceiling before offer night. Write it down. Share it with your agent and your co-purchaser. Then stick to it.
Mistake 5: Underestimating Closing Costs
On a $1M purchase in Toronto, closing costs beyond the down payment can easily reach $35,000–$45,000. The two biggest surprises are Ontario’s Land Transfer Tax and Toronto’s additional Municipal Land Transfer Tax. First-time buyers can receive rebates of up to $8,475 (provincial) and $4,475 (municipal), but must apply—they aren’t automatic.
5 Seller Mistakes
Mistake 6: Overpricing in Search of the “Right Buyer”
Overpricing doesn’t result in a higher sale—it results in stigma. According to TRREB market data, homes on the market beyond 30 days typically sell 5–8% below comparable properties that were correctly priced from day one. The longer a home sits, the more buyers assume there’s a problem with it.
Correct pricing attracts the right buyers at the right time—when momentum and interest are highest. Price it right from the start.
Mistake 7: Listing Without Preparation
Buyers form first impressions in seconds—both online (through listing photos) and in person. A $1,500 investment in professional photography, deep cleaning, and minor repairs can generate multiple competing offers and add $10,000–$30,000 to the final sale price. Sellers who skip this step leave money on the table.
Mistake 8: Refusing All Conditional Offers
In a more normalized market like 2026’s GTA, insisting on unconditional offers only may mean waiting months for a buyer willing to take that risk. Evaluate conditions individually: a 3-business-day financing condition from a pre-approved buyer is very different from a 10-day condition with no pre-approval. Negotiate the terms, not just the price.
Mistake 9: Failing to Disclose Known Defects
Ontario sellers are legally required to disclose known material defects. Concealing issues like water infiltration, structural problems, or previous flooding creates post-closing legal liability that can far exceed the cost of the original repair. The Seller Property Information Statement (SPIS) is the tool for disclosure—complete it honestly.
Mistake 10: Being Present During Showings
Sellers who remain present during showings make buyers uncomfortable. Buyers can’t speak freely about the home’s pros and cons, often cutting visits short without fully engaging. The result: fewer offers and weaker interest. Step out during all showings and open houses. Your agent handles the presentation.
Frequently Asked Questions
Q: What’s the single biggest mistake to avoid when selling in 2026?
Overpricing. In a buyer-favoured market, inventory is high and buyers have choices. An overpriced listing will sit and develop stigma faster than in previous years. Work with your agent to price based on recent sold data—not what a neighbour listed for, and not what you paid.
Q: Should sellers wait for the market to improve before listing?
Only if you’re also not buying. If you’re selling to buy, market conditions affect both transactions equally. What matters is the spread between your sale price and your purchase price, not the absolute market level.
Q: Can I skip hiring a buyer’s agent to save money?
In most Ontario transactions, a buyer’s agent is compensated from the seller’s proceeds—so the service is effectively free to you. Going unrepresented means you’re negotiating against a trained professional representing the seller’s interests. The cost savings are illusory; the risk is real.
